The first living organisms simply replicated themselves like carbon copies. It was easy and it was fast. Until 1.3 billion years ago, when something new happened.
Sex!
Some organisms first needed to find a mate in order to reproduce. It was slow, because not all progeny were female, which slowed the process down. So, why the change? Why did this new idea survive and become so successful? What were the benefits over a fast copying system that could populate more quickly?
Sexual reproduction meant that an organism could combine half of its genes with half of another’s genes, which creates new combinations for each generation. Though slower, sexual reproduction results in offspring that can do more than its parents.
Shuffling and recombining genes creates complexity, but also more ways to survive a changing world. Nature is not static. If you can mix genes, there’s a better chance your offspring will survive. Sexual reproduction started becoming successful because organisms began to design more ways to find food, manage pathogens, and attract the best mate. Genetic diversity meant that a species could change over successive generations.
